The drought
Since 2012, South Africa has received less rainfall than the average annual rainfall,
which is just over 600 mm. Figure 1 shows why 2015 can now officially be declared
the driest year in South Africa since the recording of the annual total rainfall began in
1904:

The information in Figure 1 is mirrored by the Standard Precipitation Index (SPI), which
shows deviations from average long-term rainfall patterns. The Bureau for Food and
Agricultural Policy (BFAP) explains that the index observes under-average rainfall
patterns on a monthly basis and indicates the severity of a drought3. Figure 2 below
shows the SPI for South Africa for October, November and December 2015:
